Installation and calibration of Azbil Corporation Smart Valve Positioner
100 Series
The SVP is designed to withstand severe operating conditions. Still, the installation location
must satisfy certain criteria or unexpected operation may result. The Smart Valve Positioner
100 Series is designed to operate:
„
in ambient temperatures of -40°C to +80°C
„
in relative humidity of 10 to 90%
„
where there is no chance of sudden temperature and humidity changes
„
where magnetic field induction is not more than 400A/m.
„
Avoid installing the SVP near a large transformer, high-frequency furnace, etc.
„
For HA Actuators, vibration cannot be more than 2G (5 to 400 Hz)
Azbil Corporation’s Smart Valve Positioner 100 Series are designed for use in combination
with a control valve that uses a direct- or reverse- acting or rotary actuator. The main SVP unit
weighs about 1.7 kg. It should be attached in the same way you would attach a conventional
electropneumatic positioner.
WARNING
When attaching the SVP, take every precaution to avoid physical injury. Be aware of sharp
objects such as the edges of the cover and any sharp edges on the unit. Setting up the SVP
includes opening and closing the valve several times, often unpredictably. Take appropriate
measures to prevent injury to personnel and adverse effects on the process.
The type and size of the actuator determine the type of mounting plate as well as SVP settings.
If you ordered your SVP with the actuator type specified, then the SVP should come with the
proper mounting kit, and the correct actuator settings should already be programmed into
the SVP. The Auto-setup program is then used to calibrate the SVP. Be aware that incorrect
settings not only reduce the SVP’s effectiveness, but may also cause damage to or failure of the
SVP.
If you are removing the SVP from an existing valve, first disconnect any operating lines
providing air pressure, electric power, or a control signal to the positioner.
When the SVP is installed in a hazardous environment, (e.g. corrosive atmosphere), shutting
off the air supply is not recommended unless the SVP is being removed. The air pressure
prevents corrosive gas from entering the SVP.
